V-Ray on GPU will swap in the sense that it offloads textures out of the GPU and then re-uploads them later for another bucket while still rendering the same frame. And you know, just because everyone is adding GPU support doesn't mean that professionals will switch their entire pipeline and render farms on their heads just to use it. I acknowledge that they have GPU support and that some people like it, but I personally can usually not use it, so it is also not a purchase decision for me. Plus, people already have large farms of high-memory high-CPU servers without GPUs, so switching would require lots of expensive hardware purchases. And you usually render so many frames in parallel that it doesn't really matter if the single frame takes 5 minutes or 50 minutes. You just fire up 10x more servers and your total wait time remains the same.
